Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Gloriosa daisy are a species of Rudbeckia known for their large flowers in a variety of warm tones. Blooming from mid to late summer and sometimes into the fall, colors range from clear oranges to russet reds, mahogany to brown, many with colored striations on their petals or different-colored eyes. Foliage is lance-like and deep green. Somewhat shorter-lived than R. fulgida or nitida, they are still lovely additions to a summer garden. Heights depend on variety, but generally 20 to 36 inches tall and wide. Slightly less drought tolerant than the other species.
Grow in well drained soil and in full sun. Tolerates a range of soil types, including clay soil, dry soil, shallow soil, rocky soil. Drought and heat tolerant. Though prefers full sun, will tolerate a little shade. Rhizamatous habit means it spreads to form dense colonies, so just plan accordingly when you plant it. Leave flower stalks all winter as the seeds will feed the songbirds and provide winter interest. Cut back stalks and old foliage in late winter. Drought tolerant once established, but blooming period will be longer and more flowerful if watered periodically.
